A facility used 1,000,000 kWh last year. If energy efficiency measures reduce this by 12%, what is the expected consumption this year?

Explanation:
Applying a percentage decrease to a total means reduce the original amount by that percent of the original. Here, 12% of 1,000,000 kWh is 120,000 kWh. Subtracting that from the original gives 1,000,000 − 120,000 = 880,000 kWh. You can also see it as multiplying by 0.88: 1,000,000 × 0.88 = 880,000. So the expected consumption is 880,000 kWh. The other values would come from different reductions: 900,000 kWh if the drop were 10%, 1,000,000 kWh if there were no change, and 780,000 kWh if the drop were about 22%.
